In <br /> the event of a high-water condition,activation of a"silence" switch will bypass the horn and <br /> leave the visital alarm on. Any recurrence of the high-water condition will automatically <br /> reactivate the horn and light. Alarin panels that are mounted indoors n?ay be used lar addiftai to, <br /> bast â–ºaot instead of'tlae exterior alarm panel. <br /> PUMP CONTROLS (FLOATS) Electrical control floats or similar devices designed for detecting <br /> effluent levels shall be provided to activate and deactivate the pump, The purnp-off elevation <br /> shall be set to keep the pump submerged at all times. A separate float to activate the high-water <br /> alarm shall be set to activate within G inches of the pump-on elevation. Underwriter's Laboratory <br /> or an equivalent third Marty electrical shall list the level sensing devices testing and listing agency. <br /> The floats shall be supported utilizing durable, corrosion resistant material, and shall be <br /> adjustable,removable, and replaceable without requiring dewatering,entrance into the tank, or <br /> pump removal. An acceptable method would be to provide a PVC vertical weighted pipe with <br /> the float cables secured at the proper elevation using"all stainless steel" clamps at the float <br /> pivot points. Came must be taken to ensure that the shraay)edge of the clamp does not bear oar the <br /> 10re insidaation. Plastic tie-warps alone, or strappingfloaats to the discha,ge pipe are not <br /> acceptable. <br /> CONDUCTORS (WIRES) shall be conveyed to the disconnect enclosure through watcrpreof, <br /> gasproof,and corrosion-resistant conduits. Wirc grips, duct seal, or other suitable.material shall <br /> be used to seal around wire and wire conduit openings. 'There shall be no splices within the pump <br /> tank or tank access risen. <br /> When necessary OF specified, the tanks and control panel shall he protected from vehicular traffic <br /> by constructing guardrail or bollards. <br /> GENERAL DRAINFIEL,D RE UIREMENTS AND BEST CONSTRUCTION <br /> PRACTICES <br /> 1. Any clearing or preparation of the nitrification field shall be done without removal, <br /> disturbance,or compaction of soil. The contractor shall establish and stake the contour lines of <br /> the drainfield area before the installation and before the preconstilaction conference, when <br /> required. 'free or sediment protective fencing shall be installed around septic area to <br /> elitttinate construction traffic and soil compaction on se rtic -area. <br /> 2. The drainfield lines shall be installed shallow, and an contour, Drainfield trenches shall be <br /> installed level and shall follow the ground contours. An engineer's level or laser shall be used in <br /> staking and constructing the lines, Trench depth shall not exceed the maximum specified on the <br /> Construction Authorization,unless otherwise specified, (i.e. ultra-sliallow systems). Trench <br /> installation specifications from product manufactuters shall be followed. <br /> 3. No construction or backfilling shall be done when soil conditions are wet enough to cause a <br /> smearing or compaction of the soil in the drainfield or repair area. <br /> 4. The pipe between the septic, tank and drainfield, or between the septic tank:and pump tank <br /> shall be a minimum of 3" schedule 40 PVC or equivalent, with a minimum fall of 118" per foot. <br /> All joints horn the septic tank to the drainfield shall be watertight, The pipe shall be on a firm, <br /> Project#320059 <br />
